Cement Clinker Calcination in Cement Production Process | AGICO Cement
The cement clinker calcination is an important step in the cement production process. It mainly occurs in cement kiln and can be roughly divided into six reaction stages, namely drying, preheating, chemical decomposition, exothermic reaction, sintering and cooling.
Advanced Process Control for Clinker Rotary Kiln and Grate …
The cement industry includes energy-intensive processes, e.g., clinker rotary kilns and clinker grate coolers. Clinker is obtained through chemical and physical reactions in a rotary kiln from raw meal; these reactions also involve combustion processes. The grate cooler is located downstream of the clinker rotary kiln with the purpose of suitably …
